Abstract
The existing Single Sign-On (SSO) schemes are based on PKI/PMI, WS-Security, Kerberos etc. But they can`t support Trusted Network Connect (TNC). To make up for the shortage, a multi-authentication modes SSO scheme based on TNC named SSO-TNC is proposed. SSO-TNC uses an authentication gateway to realize SSO by loading different authentication plugins, issuing Cookies and binding the original accounts of applications. Furthermore, SSO-TNC combines Federated TNC (FTNC) to implement the SSO across domains based on security certificate. The experiment results show that SSO-TNC can effectively solve the SSO problem in the TNC environment, and provide better security, availability and scalability. Keywords-Trusted network connect, Single sign-on, Multiple authentication modes
